I am seeing two behaviors with tags and Gmail that are not
great, although not fatal, either.
First, if I tag an email in MailMate, and then go to the Tags
preference panel and give that tag a Gmail equivalent, MailMate
removes the tag from all emails with that tag. I am not touching
the Display or IMAP Keyword column, merely typing something into
the gmail column, and the original tag goes poof. If I re-apply the
tag, it sticks, and properly tags on Gmail as well.
Second, I am not getting gmail (web client) to Mailmate tag
syncing unless I also change the tags on the MailMate side. That
is, when I make a tag change on MailMate, it appears on Gmail as
well (presuming I have filled in the Gmail column in the tags
preference panel). But when I make a change on the Gmail side,
using the Gmail web app, the revision doesn't appear on MailMate. I
can sync the account, quit and restart Mailmate, open the email,
the Gmail tag revision does not appear. Only if I make a change to
the tags for that email using MailMate (any change, not necessarily
duplicating the change I made on Gmail) does it re-sync with
Gmail.
Perhaps these are both working as intended, but they are
annoying and potentially problematic in my workflow, so if there is
a way I can avoid this problems, I would be grateful to have it
pointed out. I am subscribed to Gmail/All Mail, as recommended in
the manual, but both these problems existed before and after I
subscribed.
